NELSON B. HENRY, OF DALLAS, TEXAS, ASSIGNOR TO THE MURRAY COMPANY, OF DALLAS, TEXAS.

' Be it lmown that I, NELSON B. HENRY, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas,'have invented certain new and useful. Improvements in Gins, of which the following is a specification.

My invention has relation to that class or type of machines known as cotton gins or to analogous machines known as linters and in such connection it relates more particularly to certain arrangements of parts and details of construction of such gins or linters. I

F In this connection the present invention .relates to that type of machine wherein the lint is removed from the saws by means of f a blast of air generated in a source outside the machine, in contradistinction to that type of machine in which the lint is removed by revoluble brushes or other me-- chanical means which may or may not set up in the machine an air current to assist in the removal of the lint.

One of the main objects of my present invention is to arrange and construct the air blast device so that with its side closures and with the legs it comprises the frame work of the gin or linter, the air device becoming a part and parcel of the ginsor linters and is supported by and secured to the legs of the gins or linters.

A secondary object of my present invention is to so arrange and construct the saw shaft that it is readily adjustable with regard to the air ducts leading from the saws which ducts are immovable or fixed with relation to said saws.

A further object of my invention is to so construct and arrange the air ducts as to provide an inlet and an outlet. duct formed of three walls, the intermediate wall forming a partition separating the inlet from the outlet ducts and all three walls being so arranged at their ends as to be readily riveted or otherwise fastened to trough like pieces forming side closures which in turn are held to position by the legs of the gins or linters.

With the above and other novel features in view, my invention has relation to certain Specification of Letters Patent. Application filed January 5, 1915. Senal No. 613.

novel features of construction and use, ex-

amples of'which are described in the following specification and illustrated in the.

F 1g. 6, 1s a view similar to Fig. 5 but with the section taken on line 01, d of Fig. 2. Fig. 7, is adetail view, sectioned on line 6, e, of Fig. 2 illustrating the connection between the lint dis charge duct and the lint flue. Fig. 8, is a detail view, sectioned on line f, f of Fig. 3

illustrating the construction of. the two air ducts and means for connecting the walls thereof to the legs of the machine. Fig. 9, is a-view sectioned on line 9, g of Fig. 3, illustrating the construction of the end of the air ducts adjacent to the saws, and Fig. 10, is a cross sectional view corresponding to Fig. 3, but illustrating a linter with the air blast pipe and ducts connected therewith.

Referring to the drawings 22, represents thetwo legs of the machine resting upon the floor and forming as at 3, 3, the

end bearings for shaft 4 which carries the saws 5. To the rear of and slightly below the bearings 3 for shaft 4 are arranged in the legs 2, 2 the bearings 6, 6 for the dirt and mote conveyor 7.

vAt the front of the machine, above the saws '5 is arranged the roll box 8 for seed cotton,-the base of said box 8 being traversed by said saws 5. The saws 5 project through the usual ribs -9; and from the roll box 8 extends the seed chute 10.

So far as describedand as illustrated, the various parts and their accessories are constructed and arranged to operate in the usual and well known way and are not of themselves claimed as new. They, however,

vice, to be hereinafter described, a portion of my invention.

Referring now to the air blast and air duct devices it will be seen that the legs 2, 2 are formed or shaped, at the rear of the machine, to receive the air blast pipe 12 which traverses the legs longitudinally of the machine. A preferred way of supporting the pipe 12 in the legs 2 is shown in Figs 2 and 5. The legs 2 have a semi-circular flange 13 partly inclosing the nippel 14 forming a prolongation of one end of the air pipe 12 and forming a means of connecting said pipe 12 with the air conveyer 20.

I The nipple 14 has a flange 15 by means of which it may be bolted as at 16 to the semicircular flange 13 of leg 2. The nipple 14 also has a second downwardly extending flange 17 arranged to be bolted by bolts 18 to the leg 2. The downwardly extending flange 17 forms as hereinafter described a side closure for the inlet andoutlet air ducts.

Referring now to Fig. 3, the air blast pipe I 12 opens into a chamber 21 from Which extends an upwardly curved air inlet duct 22 leading directly to a point in alinement with the axis of rotation of the saws and adjacent to the teeth of saws 5. At its extremity it is curved as at 23 and extends backward to form an outlet duct 24 leading from the saws 5 to the lift flue 25. The duct 22 is separated from the duct 24 by a partition 26 of sheet metal riveted or otherwise secured to the box like frame 17, forming the side closure for the ducts 22 and 24, (see Fig. 8) This partition 26 forms therefore one wall for duct 22 and one wall for duct 24. The

other wall 27 for duct 22 is preferably of sheet metal and riveted as at 29 to the box frame 17 while the outer wall 30 for duct 24 is likewise preferably of sheet metal and riveted as at 31 to said box frame 17. It

will thus be seen that the air blast" device is sheathed by walls 27 and 30 to form an air compartment which is divided by partition 26 into two ducts 22 and 24forming a con- ;tinuous passage from blast pipe 12 to saws 1 construction the inlet duct 22 is provided with a contracted or nozzle like discharge end which opens upon the periphery of the saws 5 and directs thereon the air from the air blast pipe, with accelerated velocity,

upon the lint on the saws to blow the same directly into the outlet duct 24. The inlet end of the duct 24 is enlarged or cut away so as to inclose or partly inclose the saws 5 at their perimeter for approximately 45 degrees to thereby aflord an ample entrance for the lint to said duct 24. This contracted nozzle 33 while it increases the velocity of the two end frames 17 extending as flanges from the nipples 14 serving to connect the air blast pipe 12 with the air conveyer 20,

and preferably integral with said nipples 14. Each end frame 17 is shaped to conform to the shape assumed by the air chamber and air ducts as clearly indicated in main Figs. 2'and 4 and inthe sections Figs. 5, 8 and 9 taken at various points along the course of said ducts. Each end frame 17 is semi-box .shaped in cross-section having the ends 34 and 35 resting against the legs 2 of the machine. These ends 34 and 35 support the top sheathing 27 and bottom sheathing 30 to which ends the sheathing 27 and 30 are respectively riveted or otherwise. secured. Between the ends 3435 of frame 17 and extending in the opposite direction on each frame 17 is a rib or flange 36 which ribs are arranged to support the inner sheathing or partition 26. The sheathing or partition 26 is riveted or otherwise suitably secured to the ribs 36. A series of bolts 37 traversing the legs 2 enter sockets 38 formed upon. the frames 17 to thereby bolt or secure said frames 17 to the legs of the machines.

The connection of the outlet duct 24 with lint flue 25 is well known in the art, but for convenience it has been illustrated in Figs. 2, 3, 16 and 7. It consists essentially of the following arrangement and construction of parts. The flange or end 34 of frame 17 is formed into a step like projection 40 at the outer end of the air blast device to inclose between said projection 40 and the inner partition 26 a wooden plank 41 forming one wall of the outlet duct 24. The other end 35 of flange 17 is bolted directly .to a plank 42 the two planks forming the outlet end of said duct. Each plank 40 and'41 is beveled at 42 its connection with the correspondingly beveled ends 43 of the lint flue 25. A bolt and nut 44 passing through ears 45 and 46 formed respectively on frame 17 and the frame 47 of lint flue 25 serves to clamp the beveled ends 42 and 43 respectively of the duct 24 and lint flue 25 together.

In the machine of my invention there is provided in conjunction with the fixed air blast device as heretofore described, a means for adjusting the saw shaft 4 and its saws 5 toward or away from the inlet nozzle 33 of the air duct 22 and the adjacent opening to the outlet duct 24.

In its simplest form this means consists preferably of mounting the shaft 4 in pillow blocks 50 arranged to slide upon the bearings 3, 3 of the legs 2-said bearings 3, 3

30 secured within and supported by the legs of for this purpose being elongated-and box shaped w1th upwardly extending walls 51. Through these walls 51 extend set screws or 'bolts 52 bearing at their inner ends oppositely upon the blocks '50. The unloosenlng of one bolt 52 and the corresponding tightening of the other will cause the pillow block 50 to be shifted in a direction toward or away from'the air ducts as-occasion demands. The construction is very simple and is illustrated in full lines in Fig. 2 (the .pulley etc, being partly broken awa' to disclose the adjustable bearing) an in dotted lines in Figs. 3 and 10.

In Fig. 10 the improvements of my presentinvention are shown when applied to alinter or delinting machine. It will be understood that in this instance, the saws 5 areused on one hand in conjunction with the ordinary mechanism of a delinting machine and on the other hand with an air blast device of the presentinvention.

It will be apparent, from the foregoing description, that the frame work supporting the saws, the brushes andthe auxiliary parts of the gin or linter, consists essentially of the legs, the air blast pipe, the ducts and the side closures for said ducts; and that the air blast pipe, the ducts and their closures form an integral structure removably from the saws to the discharge, Side closures for the ducts connected with the legs and forming part of the frame work of the machine, said blast pipe ducts and side closures V forming an integral structure removably se-.
